Abstract
Configurable filter bands for radio frequency communication are disclosed. In one aspect, a radio frequency module includes a plurality of n-plexers, each of the n-plexers including n filters, each of the filters configured to pass at least one radio frequency band, and at least two of the radio frequency bands having overlapping frequencies, an antenna terminal, and an antenna switch module configured to connect two or more of the n-plexers to the antenna terminal.
Claims17
A radio frequency module comprising:
- a plurality of n-plexers, each of the n-plexers including a plurality of filters, each of the filters configured to pass at least one radio frequency band, and at least two of the radio frequency bands having overlapping frequencies;
- an antenna terminal;
- and
- an antenna switch module configured to connect two or more of the n-plexers to the antenna terminal, a first one of the n-plexers including a first filter configured to pass both a first one of the at least two radio frequency bands having overlapping frequencies and a third radio frequency band different from the at least two radio frequency bands, and a second one of the n-plexers including a first filter configured to pass a second one of the at least two radio frequency bands having overlapping frequencies.

A mobile device comprising:
- an antenna configured to transmit and receive radio frequency signals;
- and
- a front-end system coupled to the antenna and including a plurality of n-plexers, each of the n-plexers including n filters, each of the filters configured to pass at least one radio frequency band, and at least two of the radio frequency bands having overlapping frequencies, an antenna terminal coupled to the antenna, and an antenna switch module configured to connect two or more of the n-plexers to the antenna terminal, a first one of the n-plexers including a first filter configured to pass both a first one of the at least two radio frequency bands having overlapping frequencies and a third radio frequency band different from the at least two radio frequency bands, and a second one of the n-plexers including a first filter configured to pass a second one of the at least two radio frequency bands having overlapping frequencies.
A radio frequency module comprising:
